DETAILED DESCRIPTION

A photographing optical lens assembly includes, in order from an objectside to an image side, a first lens element, a second lens element, athird lens element, a fourth lens element, a fifth lens element, a sixthlens element and a seventh lens element. The photographing optical lensassembly has a total of seven lens elements with refractive power.

According to the photographing optical lens assembly of the presentdisclosure, an air gap in a paraxial region is arranged between any twoof the first lens element, the second lens element, the third lenselement, the fourth lens element, the fifth lens element, the sixth lenselement, and the seventh lens element that are adjacent to each other,that is, each of the first through seventh lens elements of thephotographing optical lens assembly is a single and non-cemented lenselement. Moreover, the manufacturing process of the cemented lenses ismore complex than the non-cemented lenses. In particular, an image-sidesurface of one lens element and an object-side surface of the followinglens element need to have accurate curvature to ensure these two lenselements will be highly cemented. However, during the cementing process,those two lens elements might not be highly cemented due to displacementand it is thereby not favorable for the image quality of thephotographing optical lens assembly. Therefore, there is an air gap in aparaxial region between any two of the first lens element, the secondlens element, the third lens element, the fourth lens element, the fifthlens element, the sixth lens element, and the seventh lens element thatare adjacent to each other in the present disclosure for improving theproblem generated by the cemented lens elements.

The first lens element with refractive power has an object-side surfacebeing convex in a paraxial region thereof. Therefore, it is favorablefor avoiding overloading the refractive power on one single lens elementresulting in excessive aberrations. It is also favorable for reducingthe sensitivity of the photographing optical lens assembly.

The second lens element has refractive power. Therefore, it is favorablefor adjusting the refractive power with the first lens element so as tocorrect the aberration from the first lens element.

The third lens element has refractive power. Therefore, it is favorablefor effectively reducing the sensitivity of the photographing opticallens assembly. Furthermore, it is favorable for balancing thearrangement of the refractive powers of the photographing optical lensassembly so as to correct the astigmatism and the distortion in theperipheral region of the image, thereby improving the image quality.

The fourth lens element has refractive power. Therefore, it is favorablefor adjusting the refractive power with the third lens element so as tobalance the arrangement of the refractive powers of the photographingoptical lens assembly.

The fifth lens element with refractive power can have an object-sidesurface being concave in a paraxial region thereof and an image-sidesurface being convex in a paraxial region thereof. Therefore, it isfavorable for correcting the astigmatism of the photographing opticallens assembly so as to improve the image quality.

The sixth lens element with negative refractive power has an object-sidesurface being concave in a paraxial region thereof and an image-sidesurface being convex in a paraxial region thereof. The image-sidesurface of the sixth lens element can have at least one concave shape inan off-axis region thereof. Therefore, it is favorable for correctingthe aberration of the photographing optical lens assembly with a largeaperture. Therefore, it is favorable for evenly distributing therefractive powers of the photographing optical lens assembly close to animage surface so as to reduce the sensitivity of the photographingoptical lens assembly.

The seventh lens element with refractive power has an image-side surfacebeing concave in a paraxial region thereof. The image-side surface ofthe seventh lens element has at least one convex shape in an off-axisregion thereof. Both of an object-side surface and the image-sidesurface of the seventh lens element are aspheric. Therefore, it isfavorable for the principal point of the photographing optical lensassembly being positioned away from the image side of the photographingoptical lens assembly so as to reduce a total track length of thephotographing optical lens assembly. It is also favorable for reducing aback focal length so as to keep a compact size thereof.

When an axial distance between the object-side surface of the first lenselement and the image surface is TL, a maximum image height of thephotographing optical lens assembly (half of a diagonal length of aneffective photosensitive area of an image sensor) is ImgH, the followingcondition is satisfied: TL/ImgH<3.0.

Therefore, it isfavorable for correcting the chromatic aberration of the photographingoptical lens assembly.

When a focal length of the sixth lens element is f6, the focal length ofthe photographing optical lens assembly is f, the following condition issatisfied: f6/f<−1.0. Therefore, it is favorable for properly adjustingthe refractive power of the sixth lens element so as to reduce the backfocal length of the photographing optical lens assembly, thereby keepinga compact size.

When the focal length of the photographing optical lens assembly is f,the focal length of the sixth lens element is f6, a focal length of theseventh lens element is f7, the following condition is satisfied:−1.8<(f/f6)+(f/f7)<−0.5. Therefore, it is favorable for properlyarranging the refractive powers of the sixth lens element and theseventh lens element so as to reduce the back focal length of thephotographing optical lens assembly, thereby reducing the total tracklength thereof.

When an axial distance between the image-side surface of the seventhlens element and the image surface is BF, the focal length of thephotographing optical lens assembly is f, the following condition issatisfied: BF/f<0.35. Therefore, the back focal length of thephotographing optical lens assembly is sufficient for disposingadditional opto-mechanical components.

When a maximum refractive index of one single lens element among thefirst lens element, the second lens element, the third lens element, thefourth lens element, the fifth lens element, the sixth lens element andthe seventh lens element is Nmax, a minimum refractive index of onesingle lens element among the first lens element, the second lenselement, the third lens element, the fourth lens element, the fifth lenselement, the sixth lens element and the seventh lens element is Nmin,the following conditions are satisfied: 1.60<Nmax<1.70, and1.50<Nmin<1.60. Therefore, it is favorable for preventing the refractiveindices from becoming too small so as to correct the aberration of thephotographing optical lens assembly. Meanwhile, it is also favorable forpreventing the refractive indices from becoming too large so as to avoidexcessively small Abbe numbers.

When an axial distance between the object-side surface of the first lenselement and the image-side surface of the seventh lens element is Td, anentrance pupil diameter of the photographing optical lens assembly isEPD, the following condition is satisfied: Td/EPD<3.0. Therefore, it isfavorable for providing sufficient amount of incident light and keepingthe photographing optical lens assembly compact.

When the Abbe number of the sixth lens element is V6, the followingcondition is satisfied: 10<V6<32. Therefore, it is favorable forcorrecting the chromatic aberration of the photographing optical lensassembly.

When the focal length of the photographing optical lens assembly is f, acurvature radius of the image-side surface of the seventh lens elementis R14, the following condition is satisfied: 0.20<R14/f<0.60.Therefore, it is favorable for reducing the back focal length of thephotographing optical lens assembly.

When a central thickness of the sixth lens element is CT6, a centralthickness of the seventh lens element is CT7, the following condition issatisfied: 0.75<CT6/CT7<1.33. Therefore, it is favorable for properlyadjusting the thicknesses of the sixth lens element and the seventh lenselement. Therefore, it is favorable for assembling the photographingoptical lens assembly so as to increase the manufacturing yield rate.

When a curvature radius of the image surface is Rimg, the followingcondition is satisfied: −500 [mm]<Rimg<−20 [mm]. Therefore, it isfavorable for correcting the astigmatism in the peripheral region of theimage so as to effectively improve the image quality of the off-axis.

When an f-number of the photographing optical lens assembly is Fno, thefollowing condition is satisfied: Fno<2.0. Therefore, it is favorablefor obtaining large aperture so as to take sharp images underinsufficient light conditions by fast shutter speed.

When a sum of central thicknesses of the first lens element through theseventh lens element is ΣCT (that is, a sum of central thicknesses ofthe first, second, third, fourth, fifth, sixth, and seventh lenselements), the axial distance between the object-side surface of thefirst lens element and the image-side surface of the seventh lenselement is Td, and the following condition is satisfied:0.60<ΣCT/Td<0.85. Therefore, it is favorable for properly adjusting theaxial distances and the thicknesses of the lens elements so as toeffectively assemble and arrange the photographing optical lensassembly.

According to the photographing optical lens assembly of the presentdisclosure, the photographing optical lens assembly can include at leastone stop, such as an aperture stop, a glare stop or a field stop. Saidglare stop or said field stop is set for eliminating the stray light andthereby improving the image quality thereof.

According to the photographing optical lens assembly of the presentdisclosure, an aperture stop can be configured as a front stop or amiddle stop. A front stop disposed between an imaged object and thefirst lens element can provide a longer distance between an exit pupilof the photographing optical lens assembly and the image surface andthereby improves the image-sensing efficiency of an image sensor. Amiddle stop disposed between the first lens element and the imagesurface is favorable for enlarging the field of view of thephotographing optical lens assembly and thereby provides a wider fieldof view for the same.

According to the photographing optical lens assembly of the presentdisclosure, the lens elements thereof can be made of glass or plasticmaterial. When the lens elements are made of glass material, thedistribution of the refractive power of the photographing optical lensassembly may be more flexible to design. When the lens elements are madeof plastic material, the manufacturing cost can be effectively reduced.Furthermore, surfaces of each lens element can be arranged to beaspheric, since the aspheric surface of the lens element is easy to forma shape other than spherical surface so as to have more controllablevariables for eliminating the aberration thereof, and to furtherdecrease the required number of the lens elements. Therefore, the totaltrack length of the photographing optical lens assembly can also bereduced.

According to the photographing optical lens assembly of the presentdisclosure, each of an object-side surface and an image-side surface hasa paraxial region and an off-axis region. The paraxial region refers tothe region of the surface where light rays travel close to the opticalaxis, and the off-axis region refers to the region of the surface awayfrom the paraxial region. Particularly, when the lens element has aconvex surface, it indicates that the surface is convex in the paraxialregion thereof; when the lens element has a concave surface, itindicates that the surface is concave in the paraxial region thereof.Moreover, when the region of refractive power or focus of a lens elementis not defined, it indicates that the region of refractive power orfocus of the lens element is in the paraxial region thereof.

According to the photographing optical lens assembly of the presentdisclosure, an image surface of the photographing optical lens assembly,based on the corresponding image sensor, can be flat or curved,especially a curved surface being concave facing towards the object sideof the photographing optical lens assembly.
